Our services in Redwood City:

  • Crawl Space Encapsulation System: A complete sealing system using the CleanSpace® 20-mil vapor barrier to line the floors and walls of your crawl space. This barrier blocks moisture and outside air, reducing mold, wood rot, and musty odors while improving energy efficiency. Backed by a 25-year transferable warranty.
  • Sump Pump Installation: Professional installation of sump pump systems like SmartSump™ and UltraSump®, complete with airtight lids, water alarms, and battery backups. These systems actively remove water before it can cause damage, and are often paired with perimeter drainage for added protection.
  • Dehumidifier & Humidity Control: High-performance dehumidifiers like the SaniDry Sedona are designed specifically for crawl spaces. These systems keep humidity in check to stop mold, improve air quality, and maintain a dry environment beneath your home.
  • Structural Support Jacks: SmartJack® crawl space support posts are steel piers anchored into stable soil to lift and support sagging beams and joists. These adjustable jacks provide long-term stabilization and help restore uneven floors.
  • Crawl Space Insulation: Closed-cell, moisture-resistant insulation including SilverGlo™ wall panels and TerraBlock™ floor insulation. These materials resist mold, improve energy efficiency, and are designed to withstand crawl space conditions.
  • Mold Treatment & Cleanup: Safe application of Mold-X2 products to treat surface mold and prevent it from returning. This treatment is part of a complete system that includes moisture control to ensure long-lasting results.
  • Crawl Space Drainage Systems: Interior drainage channels or trench drains direct groundwater toward the sump pump. These systems are crucial for preventing flooding and are customized to each crawl space’s layout and water conditions.
  • Air Purifiers: Optional air purification systems improve the air flowing into your home from the crawl space. These systems help remove allergens, mold spores, and odors to create a healthier indoor environment.

I have high humidity in my house (currently 80%) likely due to a crawlspace with a ton of water when it rains. I think I need a pump installed and a barrier put in to keep the moisture in my house down. I need a quote for that job. Also would be interested in a dehumidifier for house/crawlspace.
